About Mildred Valley Thornton
Born
1890
Died
1967
Nationality
Canadian
Mildred Valley Thornton (1890–1967) was a Canadian artist known principally for portraits of First Nations people and also for landscapes. Public authority records establish her identity, nationality, and life years, while the available biographical source describes oil and watercolour as recurring media and notes her use of vivid colour. Collectors may encounter individual portraits, landscape paintings, and works on paper associated with her name. Her work belongs within Canadian art history, but the collected sources do not securely assign her to a named movement or school. Her subjects and media are therefore better supported than any broader stylistic label. Thornton's identity is reinforced by linked Wikidata, VIAF, and Library of Congress authority records. Catalogue-level questions—including chronology, exhibition history, and whether a particular work belongs to a documented group—should be checked against object-specific provenance and additional scholarly records.

Common works and media
Available biographical material associates Thornton primarily with portraits of First Nations people and with landscapes, executed in oil and watercolour. Auction and appraisal searches may therefore encounter paintings and works on paper across these subject groups. Any print, edition, mixed-media object, or unusually attributed work should be assessed from its own catalogue description rather than assumed to represent a standard part of her documented practice.
Market and appraisal context
Appraisily's artist market index contains matched public auction records for works offered under Mildred Valley Thornton's name. For appraisal purposes, the strongest comparisons are works sharing a similar medium, size, date, subject, condition, and level of attribution. A signed oil portrait should not automatically be compared with an unsigned watercolour landscape or a work carrying qualified attribution. Provenance, inscriptions, restoration, exhibition history, and catalogue references may also affect how a lot is assessed. Realized prices are useful evidence, but they should be compared on a consistent basis because auction reporting may differ and private transactions are generally absent. The available records do not support a guaranteed price prediction for an individual work.
